[CLOSED] UserControlLoader handling events define in User Control
Since moving the UserControl into a UserControlLoader, my events are not firing. I have created a sample as best I can to show the issue. Basically my UserControl raises an event that the containing page handles, which worked prior to moving it into a UserControlLoader for the issue linked below. I think the problem is basically before I had the actual user control defined in the page and now I just have a reference to the UserControlLoader and not the actual UserControl. Just not sure how to define the handler for the event in the containing page.
This is a result of having to use UserControlLoader instead of a defined user control inside of a Content tag, see:
